For the first part of the game, Alyx packs the only weaponry - you have the Grav Gun - which creates an unusual, co-dependant relationship between the two of you. In one lights-out section, she can't see to shoot and you have the only flashlight, so you're looking after each other in a challenging, dynamic way.
Valve's achievement is in creating a character you can rely on and feel protective about. Whether she's watching your back or you're saving her from zombies, she's so effective that it's easy to forget Alyx is actually electro-brained AI. She's always aware of your actions, and makes great tactical decisions.
